Description

Technical Field

[0001] The utility model belongs to the technical field of outer protective pipe production, in particular to an outer protective pipe shaping device. Background Art

[0002] The insulated outer protective pipe generally includes an inner steel pipe, an outer polyethylene plastic pipe, and an insulating material is filled in the middle. When filling the insulating material, it is generally necessary to limit the outer protective pipe to prevent it from excessive deformation during the filling process. At present, several wooden blocks are generally used for circumferential limiting. Several wooden blocks are passed on iron wire, and the iron wire is tied to the outer wall of the pipe along the circumference of the outer protective pipe. The wooden blocks are distributed in a circular array, and the iron wire is tightened to tighten and limit the outer protective pipe. Generally, multiple devices are set along the length of the outer protective pipe. The entire process of installing and disassembling the limiting device is very troublesome, and the outer protective pipe needs to be lifted before the iron wire can be fixed along the circumference. It requires the cooperation of multiple people, which affects production efficiency to a certain extent. Utility Model Content

DETAILED DESCRIPTION

[0011] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0012] Example 1:

[0013] like Figure 1 As shown, an outer protective tube shaping device includes a frame 1, a first limiting tube 2, a second limiting tube 3, a third limiting tube 4 and a fourth limiting tube 5 arranged along the length direction of the frame 1 and parallel to each other, that is, they are of the same length as the outer protective tube 7 and are parallel to the outer protective tube 7 when limiting, so as to limit it. The first limiting tube 2 is fixed to the frame 1, and the second limiting tube 3 is located directly above the first limiting tube 2. It is vertically slidably connected to the frame 1 and is fixed in position to adjust the relative height between it and the first limiting tube 2 in the vertical direction; the third limiting tube 4 is located on one side of the first limiting tube 2 in the horizontal direction, and is horizontally slidably connected to the frame 1 and is fixed in position to adjust the relative distance between it and the first limiting tube 2 in the horizontal direction. The fourth limiting tube 5 is slidably connected to the movable rod 6 and is locked in position. One end of the movable rod 6 is hingedly connected to the outside of the third limiting tube 4.

[0014] Specifically, the frame 1 is an "L"-shaped frame, which includes a horizontal rod 11 and a vertical rod 12. The first limiting tube 2 is fixed at the inner corner of the "L"-shaped frame, and the second limiting tube 3 is slidably connected to the vertical rod 12 through a second sliding sleeve 31, that is, the second limiting tube 3 is fixed on the second sliding sleeve 31, and the second sliding sleeve 31 is locked in position by a second fastening bolt 32. The third limiting tube 4 is slidably connected to the horizontal rod 11 through a third sliding sleeve 41, that is, the third limiting tube 4 is fixed on the third sliding sleeve 41, and the third sliding sleeve 41 is locked in position by a third fastening bolt 42. The lower end of the movable rod 6 is hingedly connected to the outside of the third limiting tube 4, and the fourth limiting tube 5 is slidably connected to the movable rod 6 through the fourth sliding sleeve 51. The fourth limiting tube 5 is fixed on the fourth sliding sleeve 51, and the fourth sliding sleeve 51 is locked in position by the fifth fastening bolt 52.

[0015] The first limiting tube 2, the second limiting tube 3, the third limiting tube 4 and the fourth limiting tube 5 can all be round steel tubes with certain strength and self-weight. The outer protective tube 7 is placed in the device, and the first limiting tube 2, the second limiting tube 3, the third limiting tube 4 and the fourth limiting tube 5 are adjusted to the predetermined positions respectively, that is, the outer diameter limiting requirements of the outer protective tube 7 are met, and the positions are locked respectively. At this time, the device has a good limiting effect on the outer protective tube 7. Since the round steel tube has a certain self-weight, the fourth limiting tube 5 can also be tightly pressed on the outer protective tube 7, so that no additional fixation is required.

[0016] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
